If the target is a real-time controller, to redeploy your project, open the system definition file and modify a setting, ex. the PCL rate. You can reverse the change right away and then save your system definition. Now you should be able to redeploy your project.
When dealing with the situation reported above for Windows targets, instead, editing the SDF parameters and trying to redeploy might not work. Instead, you can fix the problem with the following steps
- Disable the XNET interfaces of the SDF
- Deploy the SDF without the XNET interfaces
- Undeploy the SDF, enable the XNET interfaces and deploy the SDF back
